The seat experience device is configured to be able to perform a specific motion based on the motion detection unit detecting the motion of the seated person.

According to such a configuration, the motion of the seated person sitting on the first seat main body can be detected by the first sensor, and based on this detection, the seat experience device can be caused to perform a specific motion. On the other hand, the seated person sitting on the second seat main body can cause the second sensor to detect the motion and cause the seat experience device to perform a specific motion based on this detection. Therefore, even a person who can only perform movements that can be detected by only one of the first sensor and the second sensor can perform activities using the sheet.

For example, even people who cannot perform similar actions can share the same community through the seat and provide an enjoyable experience.

Further, the present invention for solving the above-described problems includes a seat body, a first sensor provided in the seat body for acquiring a first measurement value for detecting the motion of a person sitting on the seat body, and a seat body. a second sensor that acquires a second measurement value of a type different from the first measurement value and acquires the first measurement value from the first sensor for detecting the motion of the seated person sitting on the seat body; and a seat experience device capable of obtaining a second measurement from a second sensor. That is, one seat body may be provided with the first sensor and the second sensor.

According to such a configuration, the seated person sitting on the seat main body can cause the motion to be detected by the first sensor, and based on this detection, can cause the seat experience device to perform a specific motion, and the motion can be performed by the second sensor. It is also possible to cause the seat experience device to perform a specific operation based on this detection. Therefore, even a person who can only perform movements that can be detected by only one of the first sensor and the second sensor can perform activities using the sheet. As a result, various people can use the sheet for activities.

In the seat experience system described above, the seat experience device is desirably configured to notify the seated person of the action to be taken.

According to such a configuration, it is possible to make the seated occupant perform an action and effectively use the seat experience system.

In the seat experience system described above, the second sensor may have an amplifier circuit for bringing the amplitude of the second measured value closer to the amplitude of the first measured value.

According to such a configuration, there is no need to adjust the output of the input signal from the sensor in the seat experience device.

In the seat experience system described above, the seat experience device includes a sensor determination unit that determines whether the sensor connected to be able to acquire a measured value is the first sensor or the second sensor, and a sensor determined by the sensor determination unit. is the second sensor, a signal correction unit that corrects the magnitude of the input signal obtained from the second sensor so that the amplitude of the input signal approaches that when the signal is obtained from the first sensor. can.

According to such a configuration, by correcting the magnitude of the input signal in accordance with the characteristics of the second sensor, even when the second sensor is used in the seat experience device, it is the same as when the first sensor is used. You can make it behave like this.

You can make it behave the same way as if you did

In the seat experience system described above, a first connector having a plurality of terminals connected to the first sensor; a second connector having a plurality of terminals connected to the second sensor; and a third connector connected to the seat experience device and connectable to both of the sensors. In this case, the connection combination of the plurality of terminals of the second connector is different from the connection combination of the plurality of terminals of the first connector, and the sensor determination unit determines that the connector connected to the third connector is different from the first connector. By determining which of the second connectors it is, it is possible to determine whether the connected sensor is the first sensor or the second sensor.

The third connector has a common output terminal set to a predetermined voltage and at least one identification signal input terminal for detecting voltage, and the first connector and the second connector have a common input contacting the common output terminal. at least one of the first connector and the second connector is at least one identification terminal in contact with the identification signal input terminal, has an identification terminal electrically connected to the common input terminal, and has an identification terminal electrically connected to the common input terminal; and the second connector may differ from each other in the arrangement of identification terminals in portions corresponding to at least one identification signal input terminal.

Further, if the second sensor has an amplifier circuit for bringing the amplitude of the second measured value closer to the amplitude of the first measured value, it becomes unnecessary to adjust the output of the input signal from the sensor.

In addition, by changing the magnitude and threshold of the input signal according to the characteristics of the second sensor, even when the second sensor is used in the seat experience device, the same operation as when using the first sensor can be performed. can be made

[First embodiment]
Next, a first embodiment of the present invention will be described in detail with appropriate reference to the drawings.
As shown in FIG. 1, the seat experience system 1 of this embodiment includes a first seat A1 and a seat experience device 10. As shown in FIG.
The first seat A1 comprises a first seat body S10 and pressure sensors PS1 to PS6. The first seat main body S10 is, for example, a vehicle seat installed in a vehicle such as a vehicle, and has a seat cushion S1, a seat back S2 and a headrest S3. A plurality of pressure sensors PS1 to PS6 are provided under the skin of the seat cushion S1 and the seat back S2. The pressure sensors PS1 to PS6 are sensors for detecting the motion of a seated person sitting on the first seat body S10.

The pressure sensors PS1 to PS6 are arranged so as to be able to detect the state of the seat surface facing the seated person seated on the first seat body S10, and acquire pressure values from the seated person sitting on the first seat body S10. An ECU (Electronic Control Unit) 100 is a device that controls the operation of the first seat main body S10 (for example, an electric reclining motor and a heater (not shown)), and is capable of obtaining measured values from pressure sensors PS1 to PS6. It is connected to pressure sensors PS1 to PS6.

Each pair of pressure sensors PS1 to PS6 are provided symmetrically with respect to the center of the vehicle seat S in the left and right direction.
Specifically, the seat cushion S1 is provided with pressure sensors PS1 to PS3.

The pressure sensor PS1 is provided at a position corresponding to the lowest portion of the seated person's ischium. In this position, the load of the occupant is the greatest.

The pressure sensor PS2 is arranged slightly before the pressure sensor PS1.

Both the pressure sensor PS1 and the pressure sensor PS2 are for measuring the pressure from the buttocks of the seated person, and only one of them may be provided.

The pressure sensor PS3 is located far forward from the pressure sensors PS1 and PS2. A pressure sensor PS3 is positioned under the thighs of the seated person and is capable of measuring pressure values from the thighs of the seated person.

The seat back S2 is provided with pressure sensors PS4 to PS6. The pressure sensor PS4 is provided at a position corresponding to the back of the seated person's waist.

Pressure sensor PS5 is positioned slightly above pressure sensor PS4.

Both the pressure sensor PS4 and the pressure sensor PS5 are for measuring the pressure from the waist of the seated person, and only one of them may be provided.

The pressure sensor PS6 is arranged at a large distance above the pressure sensors PS4 and PS5. The pressure sensor PS6 is positioned corresponding to the upper back of the seated person, and can measure the pressure value from the upper back of the seated person.

In this embodiment, the seat experience system 1 provides a 100m run game using the pressure sensor PS3. In this embodiment, the pressure sensor PS3 is an example of a first sensor that obtains a first measurement value for detecting the motion of the person sitting on the first seat body S10. In the 100m run game, the seated person sitting on the first seat body S10 alternately raises and lowers their legs, causing the pressure sensor PS3 to sense the pressure, and depending on the number of steps taken by raising the legs, the display DSP of the smartphone SP is displayed. It is assumed that the character displayed above runs and competes with a smartphone SP or a character operated by another seated person (player) for 100m.

The seat experience device 10 has an ECU 100 and a smartphone SP.
The ECU 100 is connected to a short-range communication device 3A that enables short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). The ECU 100 is also connected to the pressure sensors PS1-PS6 via the connector 30. As shown in FIG. The connector 30 comprises a first connector 31 having a plurality of terminals connected to the pressure sensors PS1-PS6 and a third connector 33 connected to the seat experience device 10. As shown in FIG.
The configurations of the smartphone SP and the ECU 100 will be described later.

As shown in FIG. 2, the seat experience system 1 can also be configured by connecting the second seat A2 to the seat experience device 10. As shown in FIG. The second seat A2 is a seat different from the first seat A1, and is designed so that, for example, a disabled person who cannot move their legs can use the seat experience device 10 in the same way as a healthy person. It is.

The second seat A2 includes a second seat body S20 and infrared sensors IS1 and IS2 as an example of a second sensor.
The second seat body S20 has a seat cushion S1, a seat back S2 and a headrest S3 similar to those of the first seat body S10, and left and right armrests S4 rotatably provided on the seat back S2.

The infrared sensors IS1 and IS2 are sensors that acquire second measured values for detecting the motion of the seated person sitting on the second seat body S20, and are of a different type from the pressure sensor PS3. The infrared sensors IS1 and IS2 are provided on the second seat body S20. Specifically, the infrared sensors IS1 and IS2 are arranged on the upper surfaces of the front ends of the left and right armrests S4, respectively. The infrared sensors IS1 and IS2 are sensors that detect infrared rays, and when a hand is held over them, the voltage output by sensing a person's hand changes. In this embodiment, the signal amplitude of the second measured values of the infrared sensors IS1 and IS2 is assumed to be smaller than that of the first measured value of the pressure sensor PS3.

The infrared sensors IS1 and IS2 are connected to the ECU 100 of the seat experience device 10 via the connector 30. As shown in FIG. The connector 30 consists of a second connector 32 connected to the infrared sensors IS1 and IS2 and a third connector 33 connected to the ECU 100. As shown in FIG. The third connector 33 in FIG. 2 is the same as the third connector 33 shown in FIG. That is, the third connector 33 is connectable with both the first sensor and the second sensor. The seat experience device 10 in FIG. 2 and the seat experience device 10 in FIG. 1 are also the same. That is, the seat experience device 10 can obtain the first measured value from the pressure sensor PS3 and can obtain the second measured value from the infrared sensors IS1 and IS2.

A holder 4 for holding the smartphone SP is provided on the second sheet body S20. The holder 4 is formed by bending a wire, one end of which is fixed to the seat back S2, and the other end of which is provided with a fixing portion 4A for fixing the smartphone SP. By fixing the smart phone SP to the fixing part 4A, the seated person can see the display DSP of the smart phone SP without holding the smart phone SP in hand. Therefore, the display DSP can be viewed while the application of the smartphone SP is operated by placing the hands of the seated person over the infrared sensors IS1 and IS2.

As shown in FIG. 3 , the ECU 100 has a measured value acquisition section 110 , a processing section 120 , a communication section 130 and a storage section 190 . The ECU 100 and the smartphone SP have a CPU, a ROM, a RAM, a rewritable non-volatile memory, and the like (not shown), and each functional unit is realized by executing a pre-stored program.

The measured value acquisition unit 110 has a function of acquiring measured values of pressure from the pressure sensors PS1 to PS6 and the infrared sensors IS1 and IS2 at regular control cycles. The measured values acquired by the measured value acquisition unit 110 are stored in the storage unit 190 and used by the processing unit 120 . Note that the storage unit 190 is used to appropriately store data necessary for calculation, processing, and the like.

The processing unit 120 has a function of determining the type of sensor connected to the ECU 100, communicating with the smart phone SP, and transmitting the measured value and the type of sensor to the smart phone SP. For this reason, the processing unit 120 has a sensor determination unit 121 that determines whether the sensor connected to the ECU 100 so as to obtain a measured value is the pressure sensor PS3 or the infrared sensors IS1 and IS2.

Here, the sensor discrimination section 121 will be explained while explaining the structure of the connector 30 .
As shown in FIG. 6A, the first connector 31 and the second connector 32 are, for example, 20-pin female connectors having a plurality of terminals, and the third connector 33 is the first connector 31 and the For example, a 20-pin male connector having a plurality of terminals mateable with both of the second connectors 32 . Although the first connector 31 and the second connector 32 have holes for receiving 20 pins, not all of the holes have valid terminals therein, and unused holes may be left unoccupied. contains. As will be described later, the combination of connections between the terminals of the second connector 32 differs from the combination of connections between the terminals of the first connector 31 .

As shown in FIG. 6B, the terminals are assigned functions according to their pin numbers (No.). 1 to 12 are signal terminals. The output value of each sensor is No. Assigned from 1 to 12. For example, each of the pressure sensors PS1 to PS6 is No. 1 to 12, and the infrared sensors IS1 and IS2 are assigned No. assigned to 1 and 2 respectively

No. A common terminal 13 is, for example, a 5V terminal. No. of the third connector 33 . A terminal 13 is a common output terminal set to a predetermined voltage. On the other hand, the numbers of the first connector 31 and the second connector 32 are different. 13 is a common input terminal that contacts the common output terminal.

No. 14 to 20 are identification terminals for identifying the type of connected sensor. No. of the third connector 33 . 14 to 20 are at least one identification signal input terminal for detecting voltage for identification. On the other hand, at least one of the first connector 31 and the second connector 32 is a No. 14 to 20 have at least one identification terminal connected to the identification signal input terminal and electrically connected to the common input terminal. One of the first connector 31 and the second connector 32 is a No. 14 to 20 may not have valid identification terminals (terminals connected to identification signal input terminals).
The first connector 31 and the second connector 32 have identification terminals corresponding to identification signal input terminals of the third connector 33, that is, No. The arrangement of identification terminals corresponding to 14 to 20 are different from each other.

For example, if the number of the first connector 31 is 14 is not provided with an identification terminal to be connected to the common input terminal (No. 13). 14 is provided with an identification terminal connected to the common input terminal (No. 13). Therefore, when the first connector 31 is connected to the third connector 33, for example, as shown in FIG. The ECU 100 can determine the content assigned to LOW of No. 14, for example, that the sensor is manufactured by A company. On the other hand, when the second connector 32 is connected to the third connector 33, a HIGH signal is obtained in the ECU 100, and the sensor determination unit 121 determines No. The ECU 100 can determine the content assigned to HIGH of 14, for example, that the sensor is manufactured by B company.

Similarly, the sensor determination unit 121 determines the No. of the connectors (for example, the first connector 31 and the second connector 32) connected to the third connector 33. The type of sensor can be determined by a combination of whether identification terminals are provided on 15 to 17 or not. For example, as shown in FIG. No. 15 to 17 are not provided with identification terminals. 15 to 17 are all LOW signals, and it can be determined that the pressure sensor is connected. If only No. 17 is provided with an identification terminal, No. 17 becomes HIGH, and it can be determined that the infrared sensor is connected. Also, No. If only 16 is provided with an identification terminal, it can be determined that a heart rate sensor has been connected. For example, many types of sensors can be discriminated. In addition, No. 18 to 20 can also be set to a sensor type corresponding to a combination of HIGH or LOW signals.

When the ECU 100 is powered on and another connector is connected to the third connector 33, the sensor determination unit 121 determines the type of sensor corresponding to the connected connector, and determines the ID (identification information) of the ECU 100. ) and the determined sensor type to the smartphone SP.

Returning to FIG. 3 , the smartphone SP has a signal corrector 211 , a motion detector 212 , a game processor 213 , and a memory 290 .

When the sensors determined by the sensor determination unit 121 are the infrared sensors IS1 and IS2, the signal correction unit 211 adjusts the amplitude of the input signal from the infrared sensors IS1 and IS2 so that the amplitude of the input signal approaches that obtained when the signal is obtained from the pressure sensor PS3. It has a function to correct the magnitude of the acquired input signal.
Specifically, the signal correction unit 211 generates a corrected input signal by multiplying the input signal (value) input as a digital value by a correction coefficient. For this reason, the storage unit 290 stores correction coefficients by which signals (values) obtained from the sensors are multiplied in a table corresponding to the types of sensors. For example, the storage unit 190 stores 1 for the pressure sensor PS3, 2 for the infrared sensors IS1 and IS2, and so on.

Based on the sensor type received from the ECU 100, the signal correction unit 211 refers to the storage unit 290 and acquires a correction coefficient corresponding to the sensor. Then, the input signal is multiplied by this correction factor to generate a corrected input signal.
For example, since the correction coefficient of the pressure sensor PS3 is 1, the input signals SI _R and SI _L as shown in FIG. Further, since the correction coefficients of the infrared sensors IS1 and IS2 are 2, when the input signal as shown in FIG. It becomes a correction input signal. As a result, even if the amplitude of the input signals of the infrared sensors IS1 and IS2 is small, the amplitude can be made equal to the corrected input signal of the pressure sensor PS3, and the same threshold value SIth can be used for operation. can be detected.

The motion detection unit 212 detects the motion of the seated person based on the acquired input signal. In this embodiment, the motion of the seated person is detected based on the corrected input signal corrected by multiplying the input signal by the correction coefficient. Specifically, motion detection section 212 compares the corrected input signal with threshold SIth, and when the corrected input signal falls below threshold SIth (the corrected input signal changes from the base signal value to threshold SIth). ) to generate a detection signal. Thereby, the motion detection unit 212 can generate a detection signal as shown in FIG. 4B based on the measurement value of the pressure sensor PS3. Further, the motion detection unit 212 can generate a detection signal as shown in FIG. 5(c) based on the corrected input signals (FIG. 5(b)) of the infrared sensors IS1 and IS2. The motion detector 212 can detect the motion of the seated person based on both the first measured value and the second measured value.

The game processing unit 213 has a function of processing a game using detection signals. In this embodiment, the game provided by the smartphone SP is a 100-meter run game, and each time one detection signal is generated, the number of steps increases by 1, and each time the number of steps increases by 1, the character runs 1 m. A character on the display DSP of the smartphone SP is moved. That is, the seat experience device 10 is configured to be able to perform a specific action of making the character in the game move one step forward (running) based on the action detection unit 212 detecting the action of the seated person. there is

Since the 100-meter run game itself is not a characteristic part of the present invention, a simple example will be described. instruct the start of When the seated person selects the game start button, an explanation of how to move the character is displayed on the display DSP according to the sensor type received from the ECU 100 . For example, if the sensor is the pressure sensor PS3, an explanation such as "Raise your left and right legs alternately. If you move your legs alternately quickly, your character will run faster." If the sensor is the infrared sensor IS1 or IS2, an explanation such as "Wave your hand left and right on the optical sensor. If you wave your hand quickly, the character will run fast." In other words, the smartphone SP (seat experience device 10) is configured to notify the seated person to prompt the action. Note that these explanations may be output by voice.

Then, the game processing unit 213 performs processing to move the character according to the detection signal until the game player runs 100m. is configured to display the time on the display DSP.

Next, an example of processing of the seat experience device 10 will be described with reference to FIGS. 8 and 9. FIG.
As shown in FIG. 8, when the power is on, the ECU 100 refers to the table described above based on the signal input from the identification signal input terminal to determine the sensor connected to the third connector 33 ( S11). Then, it is determined whether or not it is connected to the smartphone SP (S12), and if it is connected (S12, Yes), the ID of the ECU and the type of the determined sensor are transmitted to the smartphone SP, and the process ends ( S13). On the other hand, if it is determined that it is not connected to the smart phone SP (S12, No), the process ends.

As shown in FIG. 9, the application of the smartphone SP determines whether or not the ECU 100 is connected (S21), and when it is determined that the ECU 100 is not connected (S21, No), the process ends. On the other hand, if it is determined to be connected to the ECU 100 (S21, Yes), the ID of the ECU 100 and the type of sensor are received from the ECU 100 (S22). Then, referring to the storage unit 290, the correction coefficient is set based on the sensor type (S23).

Then, the game processing unit 213 urges the seated person to start the game, and when the seated person selects the game start button, the 100-meter run game is started (S24). Then, the game processing unit 213 displays an explanation of how to move the character on the display DSP according to the type of sensor (S25).

Then, when the 100m race game starts, the signal correction unit 211 corrects the input signal received from the ECU 100 by multiplying it by the set correction coefficient (S26). Then, motion detector 212 compares the corrected input signal with threshold SIth, and generates a detection signal when the corrected input signal falls below threshold SIth (S27). The game processing unit 213 rewrites the image on the display DSP so that the character advances one step (1 m) each time this detection signal is generated.

Then, the processing of steps S26 and S27 is repeated until the character runs 100m (S28, No), and when the character runs 100m, that is, when the number of generated detection signals reaches 100 (S28, Yes). , as a result of the game, the time required to run 100 m, ie, the time from the start until the number of detected signals reaches 100, is displayed on the display DSP (S29), and the process is terminated.

According to the seat experience system 1 of this embodiment described above, the following effects can be obtained.

A seated person sitting on the first seat main body S10 causes the seat experience device 10 to perform a specific action of running a character in a 100-meter race game by detecting the action of moving the legs up and down with the pressure sensor PS3. can be done. On the other hand, the seated person sitting on the second seat main body S20 causes the seat experience device 10 to detect a motion of waving his/her hand left and right by the infrared sensors IS1 and IS2, thereby causing the seat experience device 10 to run a character in a 100m race game. can make it work. Therefore, even a person who can only perform movements that can be detected only by the pressure sensor PS3 or the infrared sensors IS1 and IS2 can perform activities using the seat. As a result, various people can use the sheet for activities. For example, even people who cannot perform similar actions can share the same community through the seat and provide an enjoyable experience.

Since the seat experience device 10 notifies the seated person to perform the action, the seated person can be made to perform the action and the seat experience system 1 can be effectively used.

Also, when the infrared sensors IS1 and IS2 are used in the seat experience device 10, the signal correction unit 211 corrects the magnitude of the input signals of the infrared sensors IS1 and IS2 so as to approach the input signals of the pressure sensor PS3. can also operate in the same way as when using the pressure sensor PS3.

Further, the seat experience system 1 determines whether the connector connected to the third connector 33 is the first connector 31 or the second connector 32 by the signal input from the identification signal input terminal of the third connector 33. Therefore, even if the sensor does not have an IC chip or the like having a storage medium, the type of the sensor can be determined. That is, the type of sensor can be determined with a simple configuration.

[Second embodiment]
Next, a second embodiment will be described. In the second embodiment, only parts different from the first embodiment will be explained, and the same parts will be denoted by the same reference numerals in the drawings and the explanation thereof will be omitted.
As shown in FIG. 10 , in the seat experience system of the second embodiment, the smartphone SP of the seat experience device 10A includes a threshold value setting unit 214 instead of the signal correction unit 211 .

Threshold setting unit 214 sets the first threshold as threshold SIth when the sensor determined by sensor determination unit 121 is pressure sensor PS3 (first sensor), and sensor determination unit 121 determines A second threshold value different from the first threshold value is set as the threshold value SIth when the sensors that have detected the infrared rays are the infrared sensors IS1 and IS2 (second sensors). The second threshold value is stored in advance in the storage unit 290 of the smartphone SP according to the type of sensor, and is set to fall within the amplitude range of the input signals from the infrared sensors IS1 and IS2. Alternatively, the second threshold is calculated by averaging the high signal value and the low signal value of the input signal within a predetermined time in the past, and the second threshold is positioned between the high signal value and the low signal value. The value can also be set by calculation.

The motion detection unit 212 can detect the motion of the seated person by comparing the input signal with the threshold value set by the threshold value setting unit 214, as in the first embodiment.

In the second embodiment, as shown in FIG. 11, the smartphone SP does not perform step S23 (FIG. 9) for setting the correction coefficient, and performs step S26 (FIG. 9) for correcting the input signal by applying the correction coefficient. Instead, it is preferable to execute a process of setting a threshold value (S126).

According to the second embodiment, when the input signals SI _R and SI _L as shown in FIG. 12(a) are input, the threshold SIth is within the amplitude range of the input signals SI _R and SI _L. is set. Then, when the input signals SI _R and SI _L change from the base signal values by exceeding the threshold SIth, it is possible to generate detection signals as shown in FIG. 12(b).

As described above, in the seat experience system of the second embodiment, by changing the threshold SIth according to the characteristics of the second sensor, even when the second sensor is used in the seat experience device 10A, The same operation can be performed as when using the first sensor. In other words, the seat experience device 10A can be operated in the same manner by using a plurality of different types of sensors provided on the first seat body S10.

[Third Embodiment]
Next, a third embodiment will be described. In the third embodiment, only the parts different from the first embodiment will be explained, and the same parts will be given the same reference numerals in the drawings and the explanation will be omitted.
In the third embodiment, the infrared sensors IS1 and IS2 described in the first embodiment are the first sensors, and the pressure sensor PS3 is the second sensor. It is assumed that the output and amplitude of the pressure sensor PS3 are smaller than those of the infrared sensors IS1 and IS2 when the amplifier circuit 40, which will be described later, is not provided. In the third embodiment, the sheet provided with the pressure sensor PS3 is the second sheet, and the sheet provided with the infrared sensors IS1 and IS2 is the first sheet.

On this premise, the pressure sensor PS3 has a sensor element PS3e for detecting pressure and an amplifier circuit 40. As shown in FIG. The amplifier circuit 40 is a circuit that amplifies the signal of the sensor element PS3e in order to bring the amplitude of the second measured value of the pressure sensor PS3 closer to the amplitude of the first measured values of the infrared sensors IS1 and IS2.
The amplifier circuit 40 includes a first resistor Rm, an operational amplifier OP, a first resistor Rm, a second resistor Rpu, and a third resistor Rpd. The sensor-side resistance Rfsr, which is the sensor element PS3e, is a resistance whose resistance value changes according to changes in pressure as a physical quantity to be measured.

The first resistor Rm is connected in series with the sensor-side resistor Rfsr between the power supply Vpp and the ground GND. Specifically, the end of the first resistor Rm opposite to the sensor-side resistor Rfsr is connected to the ground GND, and the end of the sensor-side resistor Rfsr opposite to the first resistor Rm is connected to the power supply Vpp. ing.

The operational amplifier OP is an amplifier having a non-inverting input terminal (+), an inverting input terminal (-), and one output terminal. The non-inverting input terminal (+) is connected to wiring between the sensor-side resistor Rfsr and the first resistor Rm. An output voltage Vout output from the output terminal is fed back to the inverting input terminal (-) via a negative feedback circuit. The second resistor Rpu is arranged in a negative feedback circuit. A third resistor Rpd is arranged between the negative feedback circuit and the ground GND.

In such an amplifier circuit 40, the amplification factor can be changed by changing the resistance values of the first resistor Rm, the second resistor Rpu, and the third resistor Rpd.

On the other hand, although illustration is omitted, the smartphone SP of the seat experience device 10 is not provided with the signal correction unit 211 in the first embodiment and the threshold value setting unit 214 in the second embodiment.

According to such a seat experience system, since the pressure sensor PS3 as an example of the second sensor in the second seat is provided with the amplifier circuit 40, the second measured value of the pressure sensor PS3 is obtained from the infrared sensors IS1 and IS2. It is amplified so that the magnitude of the amplitude approaches the first output value. Therefore, even if the seat experience device does not correct signals or set threshold values for each type of sensor, the second seat using the pressure sensor PS3 can be used to detect the first seat using the infrared sensors IS1 and IS2. The seat experience device can be operated in the same manner as in the case. That is, in the seat experience device, there is no need to adjust the output of the input signal from the sensor.

Each sensor PS1 to PS6, IS1, and IS2 is connected to the seat experience device 10 via a connector 30. FIG.

Each sensor PS1 to PS6, IS1, and IS2 has a memory that stores sensor identification information (ID) and the type of sensor, such as whether it is an infrared sensor or a pressure sensor. By referring to the memory of each sensor PS1-PS6, IS1, IS2 via the wiring connected to PS6, IS1, IS2, the ECU 100 can identify the type of sensor connected to each wiring. It's becoming Therefore, unlike the first embodiment, the connector 30 does not need to prepare identification terminals.

As in the first embodiment, the smartphone SP stores correction coefficients corresponding to sensor types in the storage unit 290, and is configured to set correction coefficients according to the sensor types acquired from the memory. ing.

According to such a configuration, the seated person sitting on the first seat A1 can use the seat experience device 10 in the same way regardless of whether the pressure sensor PS3 or the infrared sensors IS1 and IS2 are used. Therefore, even a person who can only perform movements that can be detected only by the pressure sensor PS3 (first sensor) or the infrared sensors IS1 and IS2 (second sensors) can perform activities using the sheet. . As a result, various people can use the sheet for activities. For example, even people who cannot perform similar actions can share the same community through the seat and provide an enjoyable experience.

That is, the ECU 100 connected to the first seat A1, the ECU 100 connected to the second seat A2, and the smartphone SP connected to these two ECUs 100 by short-range communication are combined to form the seat experience device 10C.

The smartphone SP acquires the first measurement value of the pressure sensor PS3 from the first seat A1, and can move the character of the 100m run by moving the legs of the seated person sitting on the first seat A1. The second measured values of the infrared sensors IS1 and IS2 are acquired from the seat A2, and another character who is running 100m is simultaneously moved by waving the hands on the infrared sensors IS1 and IS2 of the seated person sitting on the second seat A2. configured to be able to
